The K‑1 book: from one PDF to one file per partner
A single download might hold 50 or 100 partners, each with the same page count per K‑1. The old workflow: open the PDF in a desktop editor, extract page ranges one partner at a time, and type a sensible file name for each. At a few minutes per partner, a book of a hundred K‑1s is easily an afternoon—plus the risk of mis-labeling a range. Autosplit instead sets pages per output PDF to match one partner packet, analyzes each chunk’s text, and applies a filename pattern you control (default example: tax year, form/schedule, partner, and a short entity token). You download a ZIP of correctly bounded PDFs whose names already reflect who they belong to.
How configurable file names work
After you load the file and Autosplit shows the split preview table, open the output filename options. You’ll see a live preview of the first chunk’s name and a pattern field with curly placeholders such as {partner}, {entityFull}, {entityAbbr}, {year}, {formSchedule}, {pageRange}, {chunkIndexPadded}, and related keys—click chips to insert them. The tool substitutes values it derived from that chunk’s page text (Schedule K‑1–style layouts work best for rich partner and entity fields). Names are sanitized for safe file systems. If a partner line cannot be detected for a chunk, you still get a deterministic fallback (for example a numbered “Partner” label with page span) so nothing collides silently.
Other firm-grade use cases
Consolidated brokerage or tax packets. When the institution exports repeating sections with a fixed page count, the same split plus pattern approach yields separate attachments per account or section; tune the template toward {chunkIndexPadded} and {pageRange} when the text metadata is thinner than a K‑1.
Accounts payable and statement runs. Uniform scans (for example two pages per voucher) split cleanly; combine a literal prefix in the pattern with {pageRange} or index placeholders so accounting can file pieces without generic split_01.pdf names.
Legal and compliance production sets. Equal-page volumes from vendors can be chunked for parallel review; use entity or index segments in the pattern so internal handoffs match your numbering convention, then use Autobates or your CMS if you need formal Bates labels on the final set.
HR and benefits. Repeating multi-page summaries per employee—when page count is stable—benefit from the same automation; rely on chunk order and page ranges in the pattern where participant names are not reliably extracted from text.
What to verify
Autosplit is built for equal page counts per segment. Mixed-length sections still need range-based tools (for example Autoextract) or a different source export. Always spot-check a few output PDFs and file names against the source before bulk email or portal upload—especially the first time you use a new issuer’s PDF layout.
